    hi guys, just did a VCDS scan on my 2003 S3 after my engine management light has been on and as title says i have the following code;

    16502 - Engine Coolant Temp. Sensor (G62): Signal too High

    I vaguely remember reading something about a revised coolant sensor which is intergrated as part of the coolant tank???

    could anyone else shed some light on this please?

    just did a quick search but couldnt find anything, cheers

    There is a revised coolant temp sender/switch,(green one) but its not in the coolant bottle, the sensor in there is for the coolant level...
